407940 ÷ 81 
Our goal is to divide 407940 by 81.

On to step 1:
4 divided by 81 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 81

Going ahead to step 2:
81 can be fit into 40 0 times, resulting in a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Take the next digit (7) from the dividend and append it to 40, then repeat: 407 / 81

Let's proceed to step 3:
If we divide 407 by 81, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 5.0
The remainder is 2 after subtracting 405 from 407.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 81

Let's proceed to step 4:
81 goes into 29 0 times with a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 50.0
Subtract 0 from 29 to get 29.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 81

Advancing to step 5:
If we divide 294 by 81, we get 3 and a remainder of 51.
Put 3 as the next digit of the answer. 
Result so far: 503.0
If we take 243 away from 294, we end up with 51.
Fetch the next digit (0) from the dividend, attach it to 51 and continue: 510 / 81

Going ahead to step 6:
The number 81 fits into 510 6 times, leaving a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5036.0
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
If we divide 240 by 81, we get 2 and a remainder of 78.
The next digit of our result is 2. 
Result so far: 5036.2
If we take 162 away from 240, we end up with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 8:
780 divided by 81 is 9 with a remainder of 51.
The next digit of our result is 9. 
Result so far: 5036.29
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 9:
If we divide 510 by 81, we get 6 and a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 5036.296
Subtracting 486 from 510 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 10:
The number 81 fits into 240 2 times, leaving a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 5036.2962
Subtract 162 from 240 to get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Advancing to step 11:
81 can be fit into 780 9 times, resulting in a remainder of 51.
The next digit of our result is 9. 
Result so far: 5036.29629
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 12:
81 goes into 510 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5036.296296
The remainder is 24 after subtracting 486 from 510.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 13:
81 goes into 240 2 times with a remainder of 78.
Record the quotient 2 as the next digit in the result. 
Result so far: 5036.2962962
If we subtract 162 from 240, we get 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Moving on to step 14:
81 goes into 780 9 times with a remainder of 51.
Write down 9 as next digit of the result. 
Result so far: 5036.29629629
If we take 729 away from 780, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Our division results in 5036.29629629 with a remaining 5.1e-08.
